Abstract
Description
本發明係關於一種熱治療針，特別關於一種電磁熱治療針。 The present invention relates to a heat treatment needle, and more particularly to an electromagnetic heat treatment needle.
現有腫瘤之熱治療方式包含微波熱療、射頻燒灼熱療及超聲聚焦熱療。其中，微波熱療與射頻燒灼熱療皆是在腫瘤內直接插入針狀電極；微波熱療利用通電後微波電極末端的微波輻射器產生熱效應，而射頻燒灼熱療則是利用電極針的射頻電流，經由離子激化轉換成熱能，造成局部腫瘤組織的凝固性壞死，從而達到對腫瘤治療的目的。但此種電極針結構複雜，安裝步驟相當繁瑣，且電極針無法重複使用，因此治療費用相當昂貴。此種電極針於腫瘤組織中所產生的溫度很高，容易往外傳遞於正常組織，造成病人較大痛楚。 Existing thermal treatments for tumors include microwave hyperthermia, radiofrequency ablation hyperthermia, and ultrasound focused hyperthermia. Among them, microwave hyperthermia and radiofrequency ablation hyperthermia are directly inserted into the needle electrode in the tumor; microwave thermotherapy uses the microwave radiator at the end of the microwave electrode to generate thermal effect, while radiofrequency ablation hyperthermia uses the RF current of the electrode needle. It is converted into heat energy by ionization, causing coagulative necrosis of local tumor tissue, thereby achieving the purpose of treating tumors. However, such an electrode needle has a complicated structure, the installation procedure is rather cumbersome, and the electrode needle cannot be reused, so the treatment cost is quite expensive. The electrode needle has a high temperature in the tumor tissue and is easily transmitted to the normal tissue, causing great pain to the patient.
高強度聚焦超聲(HIFU)是利用超聲波穿透性和可聚性的特點，將高強度超聲波穿過皮膚匯聚於深部腫瘤內，在焦點處產生瞬間高溫，直接破壞腫瘤，且照射路徑上，組織內累積之能量並不多，不至傷害正常之組織細胞。然而，治療過程中或會產生副作用，如局部皮膚燒傷、局部疼痛等。 High-intensity focused ultrasound (HIFU) is a feature that uses ultrasonic penetration and polymerizability to concentrate high-intensity ultrasound through the skin in deep tumors, producing instantaneous high temperatures at the focal point, directly destroying the tumor, and illuminating the path, tissue There is not much energy accumulated inside, and it does not damage normal tissue cells. However, side effects such as local skin burns, local pain, etc. may occur during the treatment.
因此，如何提供一種電磁熱治療針，能夠降低治療成本且避免治療過程中傷及正常組織，進而提升治療效能及 產品競爭力，實為當前重要課題之一。 Therefore, how to provide an electromagnetic heat treatment needle can reduce the cost of treatment and avoid damage to normal tissues during treatment, thereby improving the therapeutic efficiency and Product competitiveness is one of the most important issues at present.
有鑑於上述課題，本發明之目的為提供一種能夠降低治療成本且避免治療過程中傷及正常組織之電磁熱治療針。 In view of the above problems, an object of the present invention is to provide an electromagnetic heat treatment needle capable of reducing the cost of treatment and avoiding injury to normal tissues during treatment.

以下將參照相關圖式，說明依本發明較佳實施例之一種電磁熱治療針，其中相同的元件將以相同的參照符號加以說明。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an electromagnetic thermal treatment needle according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings, wherein the same elements will be described with the same reference numerals.
圖1為本發明較佳實施例之一種電磁熱治療針1之一示意圖，圖2為電磁熱治療針1的剖面示意圖。請參照圖1及圖2以說明電磁熱治療針1的技術特徵。需先說明的是，電磁熱治療針1可與一高周波加熱器(圖未示)配合使用，高周波加熱器產生一交變磁場，而電磁熱治療針1 感應交變磁場而產生一渦電流或熱能，進而達到燒灼患病組織的功效。 1 is a schematic view of an electromagnetic heat treatment needle 1 according to a preferred embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view of the electromagnetic heat treatment needle 1. Please refer to FIG. 1 and FIG. 2 for explaining the technical features of the electromagnetic heat treatment needle 1. It should be noted that the electromagnetic heat treatment needle 1 can be used together with a high-frequency heater (not shown), the high-frequency heater generates an alternating magnetic field, and the electromagnetic heat treatment needle 1 Inductive alternating magnetic field generates an eddy current or heat energy, thereby achieving the effect of burning the diseased tissue.
電磁熱治療針1包含一針體11、一披覆件12以及一握把13。針體11之材質包含至少一感磁材料，感磁材料可為金屬、合金或其組合，例如包含不銹鋼或金屬玻璃。針體11為一體成型，並具有一前端部111及一後端部112。前端部111具有一尖端T，尖端T例如為圓錐狀或多邊形錐狀。 The electromagnetic heat treatment needle 1 includes a needle body 11, a covering member 12, and a grip 13. The material of the needle body 11 comprises at least one magnetic sensitive material, and the magnetic sensitive material may be a metal, an alloy or a combination thereof, for example, comprising stainless steel or metallic glass. The needle body 11 is integrally formed and has a front end portion 111 and a rear end portion 112. The front end portion 111 has a tip end T which is, for example, a conical shape or a polygonal pyramid shape.
前端部111之一徑向寬度D1大於後端部112之一徑向寬度D2。藉此可增加前端部111所產生的渦電流及熱能，進而提升燒灼效果，但徑向寬度D1若大過徑向寬度D2太多會使前端部111與後端部112的連結強度變弱。於此較佳者為前端部111之徑向寬度D1大於等於後端部112之徑向寬度D2之2.5倍並小於等於後端部112之徑向寬度D2之5倍。在本實施例中，徑向寬度D1係以1mm~1.5mm為例，徑向寬度D2係以0.3mm~0.4mm為例。 One of the front end portions 111 has a radial width D1 that is greater than one of the rear end portions 112. Thereby, the eddy current and heat energy generated by the tip end portion 111 can be increased, and the cauterization effect can be enhanced. However, if the radial width D1 is larger than the radial width D2, the connection strength between the tip end portion 111 and the rear end portion 112 is weakened. Preferably, the radial width D1 of the front end portion 111 is greater than or equal to 2.5 times the radial width D2 of the rear end portion 112 and less than or equal to 5 times the radial width D2 of the rear end portion 112. In the present embodiment, the radial width D1 is exemplified by 1 mm to 1.5 mm, and the radial width D2 is exemplified by 0.3 mm to 0.4 mm.
前端部111係用以穿入組織內，後端部112之至少一部分係可留在組織外。若後端部112的長度太短，則針體11的應用性較差，但若後端部112的長度太長，則會影響針體11的整體結構強度。於此較佳者為後端部112之一長度L1大於等於前端部111之一長度L2之3倍，並小於等於前端部111之長度L2之15倍。在本實施例中，長度L1係以10cm~15cm為例，長度L2係以1cm~3cm為例。 The front end portion 111 is intended to penetrate into the tissue, and at least a portion of the rear end portion 112 can remain outside the tissue. If the length of the rear end portion 112 is too short, the applicability of the needle body 11 is poor, but if the length of the rear end portion 112 is too long, the overall structural strength of the needle body 11 is affected. Preferably, the length L1 of one of the rear end portions 112 is equal to or greater than three times the length L2 of one of the front end portions 111, and is less than or equal to 15 times the length L2 of the front end portion 111. In the present embodiment, the length L1 is exemplified by 10 cm to 15 cm, and the length L2 is exemplified by 1 cm to 3 cm.
此外，為增加前端部111與後端部112的連結強度， 針體之前端部111與後端部112之一連接部分113可為一多邊形柱體，例如為一梯形柱體，如此一來，從前端部111至後端部112之寬度為漸近縮小，進而能增加針體11強度。 Further, in order to increase the strength of the connection between the front end portion 111 and the rear end portion 112, The connecting portion 113 of the front end portion 111 and the rear end portion 112 of the needle body may be a polygonal cylinder, for example, a trapezoidal cylinder, such that the width from the front end portion 111 to the rear end portion 112 is asymptotically reduced. Can increase the strength of the needle body 11.
披覆件12包覆後端部112，其材質包含一非感磁材料，非感磁材料可為非金屬材料，例如為陶瓷或鐵氟龍。由於非感測材料受到交變磁場不會產生熱能，因而能避免針體11之後端部112傷及其他正常組織。披覆件12可由多種方式設置於後端部112，例如，披覆件12可藉由熔射噴塗而包覆後端部112。在本實施例中，在披覆件12包覆後端部112之後，披覆件12的表面與前端部111的表面齊平，藉以提供較佳的外觀，也可減少針體11穿入組織的阻力。 The covering member 12 covers the rear end portion 112, and the material thereof comprises a non-magnetic material, and the non-magnetic material may be a non-metal material such as ceramic or Teflon. Since the non-sensing material is not subjected to thermal energy by the alternating magnetic field, the rear end portion 112 of the needle body 11 can be prevented from injuring other normal tissues. The cover member 12 can be disposed in the rear end portion 112 in a variety of manners. For example, the cover member 12 can be coated with the rear end portion 112 by spray coating. In the present embodiment, after the covering member 12 covers the rear end portion 112, the surface of the covering member 12 is flush with the surface of the front end portion 111, thereby providing a better appearance and reducing the penetration of the needle body 11 into the tissue. Resistance.
握把13連接於披覆件12或針體11，並可直接或間接連接於披覆件12或針體11。於此，握把13係與披覆件12及針體11連接，例如針體11之後端部112可插入握把13內，而披覆件12連接於握把13之一表面。但上述連接方式僅為舉例，非以限制本發明。握把13之材質亦可包含一非感磁材料，以避免握把13產生熱能。 The grip 13 is attached to the covering member 12 or the needle body 11, and can be directly or indirectly connected to the covering member 12 or the needle body 11. Here, the grip 13 is connected to the covering member 12 and the needle body 11, for example, the needle end 11 can be inserted into the grip 13 and the covering member 12 is attached to one surface of the grip 13. However, the above connection manner is merely an example and is not intended to limit the present invention. The material of the grip 13 may also include a non-magnetic material to prevent the grip 13 from generating thermal energy.
綜上所述，在本發明之電磁熱治療針中，針體包含一感磁材料，故當其受到一交變磁場作用時，針體可由於渦電流效應及/或磁滯效應而產生熱能，進而燒灼消除腫瘤組織。此外，針體為一體成型製成，因而能提升針體之結構強度，並避免針體斷裂而能延長使用壽命。另外，針體前端部之尖端可提升針體穿透力，並且前端部之一徑向寬度 大於後端部之一徑向寬度，藉此可增加前端部所產生的渦電流及熱能，進而提升燒灼效果。此外，披覆件包覆後端部且其材質包含一非感磁材料，由於非感測材料受到交變磁場不會產生熱能，因而避免針體傷及其他正常組織。此外，本發明之電磁熱治療針具有結構簡單的優點，因而可大幅降低成本及醫療費用，並可提升治療效能及產品競爭力。 In summary, in the electromagnetic heat treatment needle of the present invention, the needle body comprises a magnetic sensitive material, so when it is subjected to an alternating magnetic field, the needle body can generate heat energy due to the eddy current effect and/or the hysteresis effect. And then cauterize to eliminate tumor tissue.
